# waterhouse [![Build Status](https://travis-ci.org/nickb1080/waterhouse.svg?branch=master)](https://travis-ci.org/nickb1080/waterhouse)

Proof-of-concept using and creating functions from another execution context. 

Doesn't work in Chrome 37 since `eval` in `iframe` contexts [is broken](https://code.google.com/p/chromium/issues/detail?id=412173). 

Works in 38+ and at least Node `0.10.32`

Here's a browser snippet to test support (`true` if supported, else `false`):

```js

(function testIFrameEval () {

  var frame = document.createElement('iframe');

  frame.style.display = 'none';

  document.body.appendChild(frame);

  var win = frame.contentWindow;

  win.eval("var evalInFrame = true");

  var result = win.evalInFrame;

  document.body.removeChild(frame);

  return !!result;

})();

```
